Outline of Final Research Achievements |
We have generated a novel transgenic rat system that enables the visualization of c-fos expression, using an enhanced green fluorescent protein (eGFP) tag (c-fos-eGFP transgenic rat). Furthermore, we have generated rats bearing an c-fos-channelrhodopsin 2 (ChR2) -eGFP fusion transgene (c-fos-ChR2-eGFP transgenic rat). The purposes of the study were to visualize the mechanism of acceptance against nociceptive stress and to try operating the neural activities of Fos-ChR2 expressing neurons by light irradiation, using these transgenic rats. We succeeded in visualizing the c-fos-eGFP expression in the hypothalamus, spinal cord, anterior pituitary, and adrenal cortex after nociceptive stress in in vitro or ex vivo in c-fos-eGFP transgenic rats. In addition, ChR2-eGFP expression on the cell menbrance in the hypothalamus and the spinal cord was observed after nociceptive stress in c-fos-ChR2-eGFP transgenic rats.
